I need a slow C# function

Question

For some testing I\'m doing I need a C# function that takes around 10 seconds to execute. It will be called from an ASPX page, but I need the function to eat up CPU time on

Answer 1

This is CPU intensive on a single thread/CPU, and lasts 10 seconds.

var endTime = DateTime.Now.AddSeconds(10);

while(true) {
   if (DateTime.Now >= endTime) 
      break;
}

As a side note, you should not normally do this.
